Too much sound attenuation

HP SOUND (green) = Very disappointed, sound attenuation is huge, we could barely hear the sound that arrives at the same headset with volume up, plus the adapter generates a steady sizzle "tic tic tic tic" very inconvenient when listening.
HIS HELMET (pink) = Microphone sound is very mitigated, the party can not hear the conversation well, like I was "in a box" or away from the microphone.
I recommend this product for the use described above.
